MAYONNAISE-MIXER.

Application filed April 29,

T0 allwhom it may concern:

Be it known that I, JAMES V. DAILEY, a citizen of the United States, and a resident of lValkersville, in the county of Silv erbow and State of Montana, have invented certain new and useful Improvements in Mayonnaise-Mixers, of which'the following is a specification.

This invention relates to an improvement in beaters for making mayonnaise dressing and one of the principal objects thereof is to provide means whereby the olive oil may be fed in the desired quantity to the dressing while it is being whlpped.

Another object of the invention is to pro vide an attachment for an egg beater for holding the olive oil and having means for feeding it drop by drop during the process of whipping the mixture.

A further object of the invention-is to provide an improved device of the class described which will be exceedingly simple, durable, efiicient in operation and inexpensive to manufacture.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction combination and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accom panying drawings in which like characters of reference indicate like parts throughout the several figures, of which- Figure 1 represents an elevational view of a beater showing the invention in place thereon,

Fig. 2 represents a vertical sectional view thereof,

Fig. 3 represents a view inperspective, the cup being removed, showing the supporting clip in place on the beater.

The invention is in the nature of a cup for holding salad oil, equipped with a valve controlled discharge opening through which the oil may drop, and a supporting clip attached to the frame of an ordinary egg beater and removably receiving a supporting tongue carried by the cup whereby the cup may be detachably mounted on the beater.

Referring more particularly to the drawing, 1 indicates the cup which in the present instance I illustrate as being in the shape of a funnel. The cup has a supporting arm 2 mounted thereon in parallel relation to the axis of the cup, the lower end of the arm bebeater.

ing free. A supporting bracket or clip indicated generally at 4 is' attached by means of bolts or other suitable devices to the frame of the beater 5, and into this clip the supporting arm 2 detachably engages for removably securing the cup in place on the beater.

The clip is stamped from a semi-circular plate of metal in such manner as to form a central or body portion 6 having inwardly offset and laterally extending ears 7 pro vided with openings for receiving the fastenlng means. These fastening means extend through the openings in the ears and through registering openings provided in the frame of the beater, for securing the clip 1n place. The central or body portion of the clip has a bar 8 stamped outwardly therefrom, and the supporting arm, when the cup is to be placed on the beater, is passed be tween the bar 8 and the body of the clip and s thus held in place. An outwardly extendlng lug 9 stamped from the lower edge of the body portion forms a stop against which the end of the arm rests. It will be noted that the stop prevents the arm from engaging with the gear 10 of the beater and thereby interfering with the operation of the The lower end of the cup is closed by a plug 11 having a reduced upper end extending into the cup and forming a shoulder 12 against which the lower end or edge of the cup tightly fits. The plug is provided with a bore 13 having the lateral branches or openings 13 communicating with the in terior of the cup. From the branch openings 13 the bore is threaded to the upper end of the plug, a seat 14 for a needle valve 15 being formed in the bore immediately below the openings 13.

The stem 16 of the valve is threaded into the upper end of the plug, said stem terminating at its upper end in a button 17, at a point above the top of the cup, whereby the valve may be conveniently adjusted by the person operating the beater. The threaded portion of the stem extends to a point well above the plug and receives a nut 18. The spiral spring 19 is interposed on the stem between the nut and the plug and this nut is screwed down to place the spring under the desired degree of tension. The spring, thus tensioned, will cause sufficient frictional engagement between the threads of the stem and plug to hold the valve in adjusted position against displacement under the influence of vibration of the beater.

In operation the cup is positioned on the beater, the valve closed, and the cup filled With the desired'amount of salad oil. The beater is then placed in the bowl in which the dressing is being mixed, and the valve opened to allow the desired amount of oil to flow either drop by drop or in a small stream into the bowl. As the beater is actuated in whipping the mixture, the valve may be quickly adjusted from time to time to regulate the flow of the oil as desired. The cup is so positioned with respect to the arms of the beater, that the oil dropping from the cup will impinge against the arms and thus be quickly whipped into the mixture.

Although I have, described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts thereof, as do not depart from the spirit of the invention and the scope of the appended claims.

I claim:

1. A device of the class described, including a cup having a plug provided with a discharge opening communicating with the cup, a needle valve threaded into the plug for controlling the flow therethrough, and operating means for the stem arranged above the top of the cup, a nut threaded on the stem, and a spring interposed between the nut and the plug and tensionable by the nut, substantially as described.

2. A device of'the class described, including a cup having a discharge opening, a

valve for controlling the passage through the opening and including a stem arranged axially with respect to the cup and provided frame of said support and having a vertical socket, a cup having a tongue fitting into said socket, said cup being agitated by the movement of the beater and being adapted to feed material to the material being beaten.
